Abstract

The utility model relates to a cyclone separation device of a dust collector. The device comprises a dust cup body; a mesh filter is arranged in the dust cup body; multiple upper meshes and lower meshes of different apertures are arranged on the upper and lower sides of a net body respectively; and the aperture of the upper meshes is less than that of the lower meshes. The device provided by the utility model has the beneficial effects that: due to the dust cup structure with cyclone separation and by taking the meshes with different apertures as the filter structure, when the dusty gas enters an air inlet, one part of the gas moves tangentially, and the other part of the gas moves downwards to enter the dust cup since the upper meshes are smaller than the lower meshes; when the gas moves downwards, the lower big meshes quickly realize separation of the dust and gas, and the dust directly enters the bottom of the dust cup; and the separated gas enters a secondary separator to prevent the dust from blocking the meshes of the mesh filter, thereby improving the separation efficiency and reducing the pressure loss.

Description

A kind of vacuum cleaner cyclone separator

Technical field

The utility model relates to the vacuum cleaner cyclone isolation technics, relates in particular to a kind of vacuum cleaner cyclone separator.

Background technology

Dust catcher can be divided into vertical, horizontal and portable by structure, its operation principle is to utilize the motor drives blade to rotate at a high speed, in the housing of sealing, produces air negative pressure, draws the dirt bits; In addition, the dust catcher technology for example, also can make air at the inner whirlwind that forms of dust catcher through changing the structure of improving dust-collecting box also in continuous renewal, and dust-separating and air are more lasting with the suction that guarantees dust catcher through the principle of centrifugal force better.But; On the dust catcher technological layer, especially use the cup type dust catcher of dirt that mesh filter is carried out cyclonic separation, because the aperture of separator air intake mesh is generally all identical; Wide-aperture mesh is poor for little dust treatment effect; The mesh of small-bore then is adsorbed on above the filter for big dust easily, makes pressure loss bigger, and is also bad to the separating effect of dust simultaneously.Therefore, in conjunction with above aspect, need reasonably improve prior art.

The utility model content

To above defective, the utility model provides a kind of can realize rapidly that dust is separated from the gas, prevent that dust from stopping up the mesh of mesh filter, can reduce the vacuum cleaner cyclone separator of the pressure loss, to solve many deficiencies of prior art.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of vacuum cleaner cyclone separator comprises the dirt cup, said dirt cup set inside mesh filter, and the upper and lower both sides of this mesh filter are provided with top mesh, the bottom mesh in some different apertures respectively.Said top mesh aperture is less than the bottom mesh, and the mesh of mesh filter distributes to be and becomes big from top to bottom gradually, and the mesh aperture scope of mesh filter is 2.0mm-3.0mm.

The beneficial effect of the described vacuum cleaner cyclone separator of the utility model is: through being provided with the dirt cup structure of cyclonic separation, and the mesh that adopts different apertures is as filtration device structure, and the top mesh is less and the bottom mesh is bigger; Like this when dusty gas gets into air inlet; A part is carried out tangential motion, and a part moves downward and gets into the dirt cup in addition, when entering moves downward; The big mesh that is positioned at the bottom realizes rapidly that then dust is separated from the gas, and dust directly gets into dirt cup bottom; And the air-flow after separating gets into second-stage separator, can prevent that dust from stopping up the mesh of mesh filter, has both improved separative efficiency, has reduced the pressure loss simultaneously again.

Description of drawings

According to accompanying drawing the utility model is done further explain below.

Fig. 1 is the said vacuum cleaner cyclone separator of a utility model embodiment structural representation.

Among the figure:

1, dirt cup; 2, air inlet; 3, top mesh; 4, bottom mesh; 5, the cup end.

The specific embodiment

As shown in Figure 1, the described vacuum cleaner cyclone separator of the utility model embodiment comprises dirt cup 1, and an air inlet 2 is offered in this dirt cup 1 upper end; Said dirt cup 1 set inside is the filtration net structure that has different apertures mesh; Be positioned at the upper and lower both sides of this dictyosome some tops mesh 3, bottom mesh 4 are set respectively, top mesh 3 wherein (aperture 2.0-2.3) is less than bottom mesh 4 (aperture 2.5-3.2); During use, dusty gas is through after the dirt bucket air inlet 2, through being the top mesh 3 of aperture; Below air inlet 2, bottom mesh 4 dusty gases of macropore have tangential motion, have the direction that moves downward simultaneously again; Through the gas of tangential motion, get into secondary and separate, and the dust-contained airflow that moves downward 5 directions motion at the bottom of the dirt cup; Thereby realized separating rapidly of gas and dust, dust directly gets at the bottom of the dirt cup 5, and the air-flow after the separation gets into second-stage separator; Reduce dust and stopped up mesh filter, both improved separative efficiency, reduced the pressure loss again.

Above embodiment is the more preferably specific embodiment a kind of of the utility model, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in the protection domain of the utility model.
